monotone f(x)=3x+2,x<=-1

monotone intervals

f (x) = 3 x + 2, x \leq - 1

Increasing : - \infty < x < - 1

Solution steps

Find the critical points:

x = - 1

Domain of

3 x + 2, x \leq - 1 : x \leq - 1

Find intervals:

Increasing

: - \infty < x < - 1

Increasing : - \infty < x < - 1

f (x) = 4 - x

f (x) = x^{2} + 4

f (x) = 4 x^{4} + x^{10}

f (x) = 1 + \frac{4}{x}
